Materials and Processes for Carbon Capture by Means of Adsorption

Dear Colleagues,

With many governments setting deadlines to achieve net zero carbon emission technologies (by 2050 in the UK), carbon capture from industries and large-point sources of emissions such as power plants represent the focal point to fight against current polluting activities associated with energy production from fossil fuels. Recently, gas emission control technologies have been employed widely in a variety of fields to separate gases such as CO₂, CO, SO₂, H₂S, NO_X, and H₂. However, each gas separation method has its own limitations, such as poor performance, not only in terms of cost, but also in terms of energy consumption; equipment corrosion due to the solvents in the case of separation by means of absorption; solids attrition in the case of separation with solid sorbents; etc. Thus, the selection of a good gas capture method is very significant to the various industrial processes and the scale of the separation. It is important to conduct proper analyses of the main factors that influence the process and identify the mechanisms of the different phases of the processes that will lead to success.

This Special Issue titled “Gas Capture Processes” aims to identify novel advances in the development and application of experimental and modeling work to address longstanding challenges in gas capture processes. Topics include, but are not limited to, the following:

• Gas separation from gas mixtures, influence of gaseous impurities on the overall performance of gas separation;
• Gas separation processes optimization, scaling-up and comparative analyses based on energy requirements and total gas separated per unit of used material and separator(s)/reactor(s) volume;
• Kinetic mechanisms of sorption/desorption, thermodynamics of CO₂ and other phases;
• Multiphase flow during the storing process; and
• The development of gas capture applications at different scales.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
